“A person with a magnetic timing light, the type that closes around the spark plug wire, MAY>>MAY get enough signal through the shielding to see the firing time.”
If the shielding wont let you pick up a signal, you might try clipping the whole plug wire with the plug connector off an old mag coil.
Then strip back a couple/three inches of insulation,fold that wire enough times on itself to fit the center post connector in the cap completely,and tightly.Secure with a wire tie.
Run a temporary ground wire from the lead shielding to the engine. Pop this “test jumper” on the spark plug.
You will now be able to pick up your signal. For testing purposes,on the ground only,of course.
NOTE...Make sure you connect the jumper wire from metal to the engine. Make sure this is a good ground or some ignitions will get damaged. So use Caution. You cannot put a bare wire or paper clip under a metal cap/boot. It will just short out. Just make up a apapter that plugs into boot and has a way to clip on sparkplug tip. That will give you a inch or so of ushielded sparkplug lead. JUST MAKE SURE TO USE JUMPER TO COMPLETE GROUND TO ENGINE FORM METAL BRAID OR METAL CAP. I will make one and post photos. Good to have for testing various engines. Best Regards Capt,n
